Maybe we can help you, but first a few questions.
1. How much do you know about Diesels? Alot --- Some---Not so much. Don't have to answer this.
2. Why do you think you need an IP?
3. Is or has the IP been timed?
4. Is the IP the original? Gray paint is usually original.
5. Same with the injectors?
6. Has new fuel hoses been installed between injectors,IP and filter?
7. Do you have good flow from the lift pump?
8. Is the filter clean or ever been changed?
9. Have you ever run out of fuel and still have a 1/4 tank or more left?
10. We DON'T FLAME, maybe a tiny bit.

Injectors from Accurate diesel. Seen some good reviews about them. They don't have any IP's.
